I need the following Block and Tackle balances replaced I figured the first number is the size and from what I have read the second number and letter combo seem to be the tension for the weights. I have attached a picture below.

4 - 29 3 BL
2 - 29 1 CL
2 - 27 2 DK
2 - 16 1 AL
4 - 10 1 AL

Please let me know which would be suitable for replacement.

Thank you,

Thank you for submitting your picture and your channel balance information to us.

Now that we have your channel lengths and stamps, we will need to confirm your specific bottom attachment.

Please take a look at this guide to help you determine which attachment you currently have:

After you've identified your attachment, we will then be able to determine your balance replacement Series.

Does your shoe have wings? If so, it appears you may have the 15-005 Shoe.

No no wings.

The image you uploaded above shows both the top and bottom attachments to have wings. Are those images of your current channel balances?

The handy man I tried to have fix them put the wing one on. The others he did not touch do not have wings.

If you want to replace to the original style balance system, without wings, use SWISCO balance Series 351. The Series 351 is a block and tackle channel balance with 15-002 and 19-002 fittings attached.

If you find the lengths do not match up as above, let us know the length of the balance (exclude the fittings for this measure) and remove the window sash and place it on a scale to give us the weight of the window sash in pounds. If the lengths did not match up as above, the sash weight is needed to determine the proper stamp option.
